title: Successful transcatheter closure of a residual patent ductus arteriosus with complex anatomy after surgical ligation using an amplatzer ductal occluder guided by live three-dimensional transesophageal echocardiography.
abstract: Residual patent ductus arteriosus (PDA) after surgical ligation is not common, but the anatomy of the residual duct may be distorted by the surgical ligation resulting in a difficult transcatheter closure. Such distorted anatomy of the duct may not be demonstrated by the two-dimensional transesophageal echocardiography (2D TEE). Fortunately, live 3D TEE provided the precise anatomy of the elongated distorted residual duct, and as in the case presented herein, guided the Amplatzer ductal occluder (ADO). We concluded that live 3D TEE provided novel images of complex residual ducts and successful guidance of a ductal occluder.
